Lachnus padi Hartig, 1841 nomen dubium

Lachnus padi Hartig, 1841: 368 (nomen dubium —Eastop & Hille Ris Lambers, 1972: 237). HOLOTYPE: (361 [6.11]), Prunus padus .

Lachnus pyri ( Hartig, 1841) (misspelling— Rudow, 1875: 77, “ P. padus ” identified as host).

Pterochloroides persicae ( Cholodkovsky, 1898) (misapplied junior synonym—Börner, 1952: 47, “Syn.?”).

Specimen. A single pinned alate collected on May 15, 1836 from Prunus padus in Tiergarten , Berlin, Germany .

Remarks. The specimen does not belong to the genus Lachnus . Its antennae are longer than its body, its secondary rhinaria are transverse, it lacks pigmented wings and it appears to have a waxy secretion on its legs and antennae. It is our opinion instead that the specimen belongs to the genus Euceraphis ( Walker, 1870) . Confirmation of its identity is needed, but it is clear that its synonymy with Pterchloroides persicae ( Cholodkovsky, 1898) as proposed by Börner (1952) is incorrect.
